Hi everybody!
I'm currently having a lot of issues with my 9 months old Appradio 4 unit. Some days ago, I wasn't able to make my iPhone 9.2.1 work with the unit... It seemed that the unit was unable to detect the cellphone, so I was unable to run Carplay as usual. Following Pioneers instructions, I reseted the device, restored the iPhone, changed the cable, attached it directly to the usb1 port in the radio... but nothing happened. The funny part is that if you connect the iPhone to the usb and then turn on the contact in the car, it starts charging, but no Carplay nor detection as iPhone,
